To whom it might concern,

We write to you this letter to share with you our concern regarding the dcsn's final exam which ended the semester on a very harsh tone. The exam written does not include most of the chapters we have spent weeks preparing for (workstations, cycle time..), with over than 15 points related to the old material of the midtearm. Furthermore, we understand the need to test our understanding of notions, yet, some of the questions seemed too vague and random, almost impossible to answer. We find it unfair for it to be this way since we practically focus on main points in class and in assignments, yet get something completely different in the exam that we are not prepared for. It makes our work useless and our efforts go to waste. This paper has been written with a main concern regarding the grades that would probably be very low and affect all of us. And this is why we kindly ask of you to acknowledge our statement and improve the current situation as well as the upcoming ones.
